Urgent Fire Weather Message issued by NWS Los Angeles 425 am Fri Jan 10
HIGH END RED FLAG WARNINGS IN EFFECT FOR MUCH OF LOS ANGELES
AND VENTURA COUNTIES THROUGH 6 PM FRIDAY DUE TO MODERATE TO
STRONG SANTA ANA WINDS AND LOW HUMIDITIES...
Critical Red Flag fire weather conditions will continue across much
of Los Angeles and Ventura counties through Friday due to moderate to
strong Santa Ana winds and low humidities. While winds had diminished
some last night, they have increased in strength and areal coverage
today, and will continue through early Friday morning. The strongest
winds tonight into early Friday morning will be across the
mountains (including the Santa Susanas and Santa Monicas) and
Santa Clarita Valley, where damaging wind gusts of 55 to 65 mph
can be expected, except isolated gusts 65 to 75 mph in the San
Gabriels, Santa Susanas, and western Santa Monica mountains. The
gusty Santa Ana winds have also overspread many of the typical
wind prone coastal and valley areas in LA/Ventura counties, with
gusts in the 35 to 55 mph range. With the enhanced upper level
wind support through tonight, there will be some breezy
conditions across portions of the LA Basin, especially the west
side of LA coast and Hollywood Hills. Humidity values between 5
and 15 percent will be common today and Friday across the Red Flag
Warning area, with poor overnight recoveries under 20 percent in
windy areas tonight. The increased Santa Ana winds today into
Friday morning will bring high end Red Flag conditions to the wind
prone mountains and valleys of Los Angeles and Ventura counties,
as well as the Malibu coast. The offshore winds are expected to
diminish on Friday afternoon, with an onshore wind shift likely
across many coastal and coastal valley areas.
Offshore winds are expected to weaken on Saturday. An extended period of
elevated to potentially critical fire weather conditions are in the
forecast for Sunday through Wednesday due to moderate to locally strong
offshore winds, likely peaking on Tuesday.
RED FLAG WARNING REMAINS IN EFFECT UNTIL 6 PM PST FRIDAY FOR
WIND AND LOW RELATIVE HUMIDITY FOR THE LOS ANGELES COUNTY INLAND
COAST INCLUDING DOWNTOWN LOS ANGELES...
WINDS...North to northeast winds 15 to 25 mph with gusts to 35
mph, except 20 to 30 mph with gusts to 45 mph in the Hollywood
Hills. Winds diminishing Friday afternoon.
RELATIVE HUMIDITY...7 to 15 percent today and Friday. Poor
overnight recoveries tonight.
IMPACTS...If fire ignition occurs, conditions are favorable
for very rapid fire spread and extreme fire behavior,
including long range spotting, which would threaten life and
property. There will be a high risk for widespread downed
trees and powerlines, as well as widespread power outages.
A Red Flag Warning means that critical fire weather conditions
are either occurring now, or will shortly. Use extreme caution
with anything that can spark a wildfire. Residents near wildland
interfaces should be prepared to evacuate if a wildfire breaks
out.

Drinking water source protection
Why so much ado about hazardous spills, toxic releases at WaterToday? Toxic materials pollute drinking water sources, above and below ground. Hazardous materials spills reported to state authorities are shown on our map. The Toxic Release Inventory reports industrial discharges from federally regulated sites. There are landfills that leach contaminants to groundwater, industrial point source discharges regulated by national and state permits, municipal wastewater releases, combined sanitary and storm overflows and non-point source contamination, such as nutrient leaching off agricultural properties. In our CrimeBox column we cover the unreported releases of contaminants, the criminal violations of the Clean Water Act. All of these factor in to the security of drinking water sources, the subject of interest.
Recently, WT has been looking into the incidental contamination that comes from municipal wastewater. Toxics are shedding from homes into wastewater, the remediation of this situation will through public awareness and a change in consumer behavior along with limitations imposed on the producers of consumer goods.
A growing number of states have introduced and adopted new regulations to curb the use of harmful molecules in consumer goods. Some manufacturers have been cooperative with social pressure to make products safer, others have launched lawsuits to protect their patents and profits. While the policy-makers and industry lobbyists wrestle for control of this situation, we have looked at ways the average person can manage exposure in the home. We are reminded that labeling for harmful chemicals is not required in many instances, beginning to look for independent certification for those alternative goods and products that are free of harmful chemicals.
To the degree the public chooses the safer alternative products, the local drinking water supply can be protected.
